Electrical Parameters
Pullup/Pulldown Device Behavior
Most pins of the XC2220U feature pullup or pulldown devices. For some special pins
these are fixed; for the port pins they can be selected by the application.
The specified current values indicate how to load the respective pin depending on the
intended signal level. Figure 11 shows the current paths.
The shaded resistors shown in the figure may be required to compensate system pull
currents that do not match the given limit values.
